What are you cooling with. mine runs about 70C under full load with an Intel water cooler. Not as good a cooler as I had hoped.

The consensus seems yes, quite easily, and without any changes to voltage in the 4 - 4.3 GHz range at least.

Easily. 4.3 is pretty much the minimum.

Hey Guys,
I have an i7 3820 overclocking problem and i think you guys can heelp.
After i overclockto 4.75ghz with 125 x 38, i run Prime 95 and AI suite says thatit is only running at 4.3ghz (125x 35), in the auto tuning it says the cpu ratio is 38 (4750mhz). Would you guys have any idea on why it is not doin the full 38 multi, Ram is 1666mhz 9-9-9-27.

My system Specs:
Mobo: asus p9x79(base model)
CPU: i7 3820
Ram: Kingston hyperx ddr3 16gb (4x4gb)
PSU: Corsair AX750
Cooler: Corsair h100

125X35= 4375MHz

Only use the bios to set multi and such. Go into BIOS and check what your MULTI is.

@Freeman94 : What's your settings in BIOS to run at 37x125 with only 1.28 vcore ??
I can't run it under 1.38v :-(

using EIST off / LLC high 130% / Manual DDRAM 1666 9.9.9.27 / Turbo off / C1/C3/C6 dis. / 1.20v VCCSA / PLL 1.8125 / VTT 1.20v

max i can "STABLE" is that : http://valid.canardpc.com/show_oc.php?id=2374322 Too high in Vcore.
Watercooling Corsair H100 => 82° in burst.


edit : I see "HT" is disabled on your cpu-z screen. It's helping in o/c ?

With Hyper threading off I can run 4.7 at +0.375 (which provides vcore between 1.36 and 1.376v with LLC on high) with it on I need over 1.4 and have yet to get it working with an offset voltage.

*Edit* You also shouldn't need to disable any of your sleep states or turbo.

All I changed was: disabled HT, disable speedstep (not C1E), set bclk to 125MHz, put the RAM to 1666MHz, change the multi to x37, change the VCORE. That's all I have altered. All other voltages are set at their "auto" values, no C states have been disabled.

CPU-Z and open hardware monitor report the voltage as 1.288 -- I was surprised. Maybe I just got a really good chip? smile.gif
